             Summary: query with local and remote pushes too much to remote
                 Key: TEIID-5900
                 URL: https://issues.redhat.com/browse/TEIID-5900
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 12.3.1
            Reporter: Ken Geis
            Assignee: Steven Hawkins


I have a table "A" in an Oracle database. I have a date dimension "B" in Teiid, which is a materialized view of a recursive query. The date dimension has all dates from 1950 to 2050, 36890 rows in total.

I run the following query:

{code:sql}
SELECT *
  FROM a
       JOIN b
         ON a.date_column = b.date_key
{code}

Teiid sends a query to Oracle, which I will paraphrase as:

{code:sql}
SELECT <columns>
  FROM a
 WHERE date_column IN (to_date('1950-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'), 
                       <36899 other date values!>)
{code}

Oracle breaks either with the length of the query or the number of options in the IN clause.

I thought that MAKEDEP/MAKENOTDEP/MAKEIND could help, but they didn't seem to change anything.
